WILLIAM H. GUYET'I'E AND HARRY R. GUYETTE, ST. ALBANS, VERMONT.

STANCHION.

Application filed May 18,

7 V) at! Iv/1.0m it may concern.

Be it known that we. \Vrmax n H. Gurn'rirn and Hxnnr it. (turn-rm, citizens oi the llnited States, residing at St. Albans, in the county of F ranklin, State of Vermont, have invented a new and useful Stanchion, of which the following is a specification.

The device forming the subject matter of this application is a stanchion, and one object of the invention is to provide novel means wherebythe stanchion is mounted for rotation about a vertical axis.

Another object of the invention is to provide novel means whereby the keeper of the stanchion may be controlled. and whereby the keepers of a plurality of stanchions may be controlled at once.

It is within the province of the disclosure to improve generally and to enhance the utility of devices 01 that type to which the present invention appertains.

lVit-h the above and other objects in view which will appear as the description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed. without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, a device embodying improvements hereinafter de scribed;

Figure 2 is an elevation similar to Figure 1. sundry parts being in section:

Figure 3 is a cross section taken approx imately on the line of Figure 2 and Figure 4; is a section taken on the line 14 of Figure 1.

In the accompanying drawings. the numeral 1 denotes a bottom support and the numeral 2 designates a top support. tl'iese parts being connected at intervals by up right posts 3. but one of. which is shown.

The numeral 4 designates generally, a. stanchion. including a bottom bar 5, a top bar 7 and a side bar 6. these elements being rigidly connected together as shown at 8. A recess 9 is formed in the top bar 7 and defines a stop 10 at one end of the top bar. The upper end 11 of a keeper 12 is mounted to move in the recess 9. the lower end of the keeper 12 being received in a recess 14 formed in the bottom bar 5. of the stanchion.

1922. Serial No. 561,916.

The lower end of the keeper 12 is mounted to swing on a pivot element 15 carried by the bottom bar 5 and extended across the recess 1d. Located in the recess 9 of the top bar 7 of the stanchion is an auxiliary latch 16 supported on a pivot element 17 mounted in the top bar and extending across the recess 9. The auxiliary latch 16 includes an angularly disposed linger 18. The latch 1c and its finger 18 are adapted to swing vertically in the recess 9, and in the under surface of the top support 2. a seat 19 is formed, the same being adapted to cooperate with the free end of the finger 18, in a manner which will be set forth hereinafter.

The numeral 20 denotes a hook-shaped main latch mounted to move vertically in the recess 9 of the top bar 7, the latch being fulcrumed intermediate its ends on a pivot element 21 carried by the top bar 7 and extended across the recess. The top bar 7 is supplied in its under edge with a groove 23 which receives an arm 22 on the main latch 20. the hooked end of the latch being heavy enoughso that the latch normally stands in the position shown in Figure 2 of the drawings. the arm 22 of the latch being re ceived in the groove 23.

in providing a pivotal mounting for the stanchion r. to the end that the same may swing about a vertical axis, thimbles 24: are inserted into the bottom bar 5 of the stanchion and into the bottom support 1. The thilnblcs 2% have abutting bearing heads 25. A pin 26 is mounted in the thimbles 2d. and thus the stanchion 41. at its lower end. is supported for rotation in a vertical axis. A tubular bearing 27 is mounted in the top bar 7 ot the stanchion 4: above the arm 22 of the main latch 20. the bearing having an enlarged head 28 which engages the upper edge of the top bar 7 of the stanchion. In its lower end, the bearing 27 provided with a relatively small bore 29. and in the upper end of the bearing 27 there is a larger bore 30 defining a shoulder 31. Av tubular beau ing 32 is fixed in the top support 2 and has a top flange 33 hearing against the upper edge of the part 2. The bearing 32 is journaled in the large bore 30 of the bearing 27, and includes a reduced end 3% which is journaled in the small bore 29 of the bearing 27, the bearing 32 having a shoulder 35 which co acts with the shoulder 31 of the bearing 27. The cooperation between the parts 32 and 27 is such, obviously, that the upper end of the stanchion -l; is mounted for rotation about a vertical axis. The bearing 32 and its reduced end 3-l are provided with a polygonal bore 36 in which is mounted to slide endwise, a rod 37 provided at its upper end with a head 38 having an inclined surface Mounted on the top support 1 are guides it) having rectangular openings receiving for longitudinal sliding movement but against rotatioina rod al which may be operated by a handle 42. Mounted to slide for adjustment on the rod all and held in adjusted positions by a set screw H is a block 48 having an inclined surface coacting with the inclined surface 39 of the head 38 on the upper end of the rod 37. Because the rod 37 is of polygonal cross section the rod cannot rotate in the bearing 32. Because the rod. ll, is of polygonal cross section, the rod a1 cannot rotate in the guides 40. As a consequence, the inclined surface of the block 43 is always held in such a position that it will cooperate with the inclined surface 39 of the head 318. It is to be understood that the structure above described may be duplicated to any desired. extent. so that a plurality of stanchions may be operated at once, but since there is no novelty in mere duplication the drawings have been confined to the present showing.

Let it be supposed that the keeper 12 is in the vertical position of Figures 1 and 2, and that the l1o0k-shaped main latch 20 is engaged over the upper end ll of the keeper 12, the auxiliary latch 16 hanging in the depending position shown in Figures l and 2. When it is desired to free the keeper 12, the rod all is pushed to the right and the inclined surface d5 of the block 43 cooperates with the inclined surface 39 on the head 38 incense ure 2 of the drawings, the auxiliary latch 16 is raised and the linger 18 of the latch beingreceived in the seat 19 of the topsupport 2 prevents the stanchion 4 from swinging on a vertical. axis. The upper end of the keeper 12 may be swung to the left, manually, to interlock automatically with the main latch 20.

Having thus described is claimed is:-

In a device of the class described, top and bottom supports; a stanchion including a pivoted keeper; means for pivotally connecting the lower portion of the stanchion with the bottom support; interengaged pivot elements mounted in the upper part of the stanchion and in the top support; a rod mounted to slide in the said pivot elements; a latch pivoted on the top part of the support and coacting with the keeper, the rod constituting a means for tilting the latch to disengage the same from the keeper; and an overhead actuating means for the rod.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
